How do I choose a DB engine?

You should consider the natural structure of your data, how it is structured when you write it, and how you will read it. You will need to have an idea, or at least an opinion, about how large your data set will be, both in terms of total volume and the working sets you will need.

Which DB is best for large datasets?

How big is a petabyte in data management?

Data managers don’t have a way to visualize the actual volume of data they’re dealing with, and most are just flabbergasted when they truly understand the practical implications of moving it forward into a modern backup environment or growing it under current business requirements. How big is a petabyte?

How many terabytes are in a petabyte of data?

A petabyte of data is equivalent to 1000 terabytes or 1,000,000 gigs of data storage. To put this into perspective, here are some comparisons to real world examples: The average 4k movie is 100GB of data. This would mean 1 petabyte of storage could hold 11,000 4k movies.

Is it possible to read 60 petabytes of data?

Other times, the physical media itself is aging out with the tape media disintegrating so that it is uncertain if it will be possible to read data stored on it. Until the time comes to move all that data, many customers simply think of it as a number — whether they’ve got a 200 terabyte or 60 petabyte pile of data.

How is 300 petabytes of data equivalent to moving a cube?

Using this as our metric, we can multiply copies of this book to represent the customer’s data volume. In this customer’s case, the volume of 300 petabytes of stored data is equivalent to moving a physical cube of books — about 75,000,000,000 copies.
